EstimatedPointProcess

[Experimental]

✖
EstimatedPointProcess[pdata,pproc]

estimates the parametric point process pproc from point data pdata.

✖
EstimatedPointProcess[pdata,pproc,{{p,p0},{q,q0},…}]

estimates the parameters p, q, … with starting values p0, q0, ….

Details and Options

  • EstimatedPointProcess takes point data pdata and returns the symbolic point process pproc with parameter estimates inserted for any non-numeric values.
  •     
  • In general, a process pproc can be better estimated from an ensemble of point data.
  •     
  • The points pdata can have the following forms:
  • {p1,p2,…}points pi
    GeoPosition[…],GeoPositionXYZ[…],…geographic points
    SpatialPointData[…]spatial point collection
    {pts,reg}point collection pts and observation region reg
  • The points are converted to a SpatialPointData object and a Ripley–Rasson estimator is used to generate the observation region if it is not provided in pdata.
  • The following options can be given:
  • AccuracyGoalAutomaticthe accuracy sought
    PointProcessEstimator Automaticwhat process parameter estimator to use
    PrecisionGoalAutomaticthe precision sought
    WorkingPrecision Automaticthe precision used in internal computations
  • Settings for PointProcessEstimator are documented under the individual point process reference pages.
